HONG KONG, Nov 24 (Reuters Breakingviews) - Pershing Square boss Bill Ackman is taking another tilt at the Hong Kong dollar , betting the government will be forced to break its link to the greenback. His logic is stronger today than when he took the plunge in 2011 but it’s up to Beijing, not Hong Kong. Back then Ackman famously predicted that the Hong Kong Monetary Authority would allow the local currency to strengthen against the U.S. dollar. A secular decline in Hong Kong might ultimately sabotage the peg at some point. On the other hand, Hong Kong is a city, not a country.
